    Consult a physician. Show this safety data sheet to the doctor in attendance.

    If inhaled

    Fresh air, rest.

    In case of skin contact

    Rinse skin with plenty of water or shower.

    In case of eye contact

    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

    If swallowed

    Rinse mouth. Give one or two glasses of water to drink.

    4.2 Most important symptoms/effects, acute and delayed

    no data available

    4.3 Indication of immediate medical attention and special treatment needed, if necessary

    Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Inorganic acids and related compounds/
